The subtitle says it all. The co-authors, Pepper Schwartz and Janet Lever, are PhDs and sex experts. They’ve put a huge amount of thought and research into a book crammed with irresistible ways to foster romance.

They list getaways to suit every taste—cities, natural beauty, beaches, and adventure; on every continent—well, maybe not Antarctica. A random sampling: the Great Barrier Reef, the Loire Valley, the Amalfi Coast, Marrakech, Bali, the Cotswolds. Detailed listings for each destination make planning that much easier.

The hardest part might be deciding where to go. Schwartz and Lever suggest having both partners list the three places they most long to see. With luck, the two lists will share at least one destination.

The authors acknowledge, “Keeping romance—and passion—alive over the long term isn’t impossible, but it isn’t easy, either. It’s complicated: We crave the security that comes with our committed relationship, but we also desire adventure and fresh discovery.” Traveling, including the planning and anticipation beforehand and the shared memories afterward, restores the excitement a relationship had when it was new.

Couples who share a long history are inevitably liable to “hedonic adaption”: getting so used to good things that they don’t feel good anymore. When traveling, couples encounter one surprise after another. Novelty makes the two more interesting to themselves and to each other. The authors write, “Research shows that the very best way for couples to refresh their love for one another is to do something, anything, novel together.”

Uninterrupted time away from day-to-day obligations means a chance to get to know a partner more deeply. Learning new skills, like kayaking or navigating an unfamiliar transit system, enhances mutual respect. According to the authors, a magnificent natural view “can ignite all four of the so-called love hormones: dopamine, which fosters feelings of love; oxytocin, which helps create trust and bonding, serotonin, which increases feelings of pleasure and well being; and norepinephrine, which gives us energy and is part of our sexual arousal.”
